Cobra pipes have a crossover pipe to blend the exhaust from both the front and rear cylinders. The exhaust gasses will take the path of least resistance so most will come out the bottom exhaust and be hot.

With a crossover pipe, just asking.....check for a blockage, like a rodent nest?

Seems to be some confusion here.
Cobra "Speedster" Long vs Vance & Hines Long shots or Bigshots
"Speedster" seems to be common with Cobra.

Do some temp probing around the cylinder head exhaust port.
You have a few seconds before the exhaust port gets too hot.

Verify if there is a "crossover" from top to bottom pipe.
Take a picture and post it.
